We present a system that field test of photovoltaic module. The system is used for to absorb more energy from sun. There are Maximum Power Point (MPP) can be monitoring and extract the maximum energy from sun for producing Electricity. It can use monitor performance and Long-term stability of module under realistic condition. A monitoring system consists a individual MPP tracker attached to each module under test. This system also contains a one data logger which cans Analysis and saving of data. The data logger monitoring the performance of photovoltaic (PV) module under field condition is important for both the testing of individual module and the comparison of energy yield for different types of solar cell module at certain geographic location. https://journalnx.com/journal-article/20150027
